| Abstract: | Thermolysis of Mannich Bases from β-Ketosulfoxides, Benzaldehyde and Secondary Amines By condensation of ω-(methylsulfinyl)acetophenone (1) with benzaldehyde and secondary amines stable Mannich bases 2 are obtained as mixtures of four diastereomeric forms according to the presence of three chiral centers. Amine elimination above 180°C leads to a single E-diastereomer of 2-methylsulfinyl-1,3-diphenylpropenone (3) as indicated by the 1H and 13C-NMR spectra. |
